Ordered my new 2017 MCS with BR green and white top. White top automatically came with white outside mirror covers and they look like, well, Mickey Mouse's gloves. Would like to replace them with matching green covers or maybe black.

Seems this would be an easy swap, but...I've been fooled before and don't want to destroy the original covers or foul up the mirror body with ill-advised, ham-fisted prying. Getting older and near-vision eyesight isn't good enough to see any screws, tabs, etc. (Yes I should invest in some Walmart reader specs!)

So, how do you go about this swap?

Thanks
